Short summary
The processes that establish how mixed-phase closed-cell clouds transition to open-cells are poorly known. First-of-its kind aircraft observations document such a transition in the presence of anomalously high aerosol concentrations, reducing the drop size thereby discouraging riming, over the Nordic Seas at cloud temperatures < −15 °C. Eventually, ice precipitation produces surface cold pools that appear to drive the convective transition, despite strong counteracting surface fluxes.

Short summary
Using aircraft data collected over the Atlantic Ocean, we discovered that new particles form regularly in marine air at two different heights, challenging the belief that sea salt prevents this process. These particles can grow to form cloud droplets, affecting Earth's climate. We found particles forming at two heights: where upper atmosphere air enters the ocean boundary layer and where the well-mixed surface air meets the stable air layer above. This discovery will help improve climate models.

The Fifth International Ice Nucleation Workshop Phase 3 (FIN-03) compared the ambient atmospheric performance of ice-nucleating particle (INP) measuring systems and explored general methods for discerning atmospheric INP compositions. Mirroring laboratory results, INP concentrations agreed within 5–10 factors. Measurements of total aerosol properties and investigations of INP compositions supported a dominant role of soil and plant organic aerosol elements as INPs during the study.

A modified version of a Handix Scientific printed optical particle spectrometer is introduced. The paper presents characterization experiments, including concentration, size, and time responses. Integration of an external multichannel analyzer card removes counting limitations of the original instrument. It is shown that the high-resolution light-scattering amplitude data can be used to sense particle-phase transitions.

Short summary
Inverse methods infer physical properties from a measured instrument response. Measurement noise often interferes with the inversion. This work presents a general, domain-independent, accessible, and computationally efficient software implementation of a common class of statistical inversion methods. In addition, a new method to invert data from humidified tandem differential mobility analyzers is introduced. Results show that the approach is suitable for inversion of large-scale datasets.

Short summary
This work introduces a new method that uses remote sensing techniques to obtain surface number emissions of particles with a diameter greater than 500 nm. The technique was applied to study particle emissions at an urban site near Houston, TX, USA. The emissions followed a diurnal pattern and peaked near noon local time. The daily averaged emissions correlated with wind speed. The source is likely due to wind-driven erosion of material situated on asphalted and other hard surfaces.
